The M54/74HC423/423A are high speed CMOS
MONOSTABLE
multivibrators
silicon gate C

MOS technology.
They achieve the high speed operation similar to
equivalent LSTTL while maintaining the CMOS low
power dissipation. There are two trigger inputs, A
INPUT (negative edge) and B INPUT (positive
edge). These inputs are valid for rising/falling
signals, (t
r
– t
f
– 1 sec). After triggering the output
maintains the MONOSTABLE state for the time
period determined by the external resistor Rx and
capacitor Cx.
Two different pulse width constant are available:
K
0.46 for HC423
K
1 for HC423A.
Taking CLR low breaks this MONOSTABLE
STATE. If the next trigger pulse occurs during the
MONOSTABLEperiod itmakes theMONOSTABLE
period longer. Limit for values of Cx and Rx :
Cx : NO LIMIT
